Digital Diagnostic Functions
The XFP support the 2-wire management interface which is used for serial ID, digital diagnostics, and certain control functions. It is modeled on the SFF-8472 Rev 9.3 specification modified to accommodate a single 2-wire interface address. In addition to the basic I2C read/write functionality the modules support packet error checking that, when enabled, allows the host system to confirm the validity of any read data. Details of the protocol and interface are explicitly described in the MSA. And the digital diagnostic functions via a 2-wire serial interface can provide real-time access to following operating parameters: a. Transceiver Temperature
Transmitter Section- The Laser Driver accept differential input data and provide bias and modulation currents
for driving a laser. An automatic power control (APC) feedback loop is incorporated to maintain a constant average optical power. Laser in an eye safe optical subassembly (OSA) mates to the fiber cable. TX CDR is used to overcomes host board and connector signal degradations by reshaping, regenerating, and attenuating jitter.
TXDIS- TX_DIS is an input pin. When TX_DIS is asserted High, the XFP module transmitter output must be turned
off.
Receiver Section- The Receiver utilizes a PIN detector integrated with a trans-impedance preamplifier in an OSA.
The OSA is connected to a limiting Amplifier which providing post-amplification quantization, and optical signal detection. The limiting amplifier is AC coupled to the Trans-impedance amplifier , with internal 100ohm differential termination. RX CDR is used to overcomes host board degradations by reshaping, regenerating, and attenuating jitter.
LOS- The LOS of an output pin , when LOS is high, it indicates insufficient optical power for reliable signal
reception.
MODNR- The MODNR is an output pin that when High, indicates that the module has detected a condition that
renders transmitter and or receiver data invalid, shall consist of logical OR of the following signals: a. Transmit Signal Conditioner Loss of Lock b. Transmitter Laser Fault c. Receiver Signal Conditioner Loss of Lock
Controller Section- The micro controller unit initializes the control register of laser driver, limiting amplifier and
CDR. And monitors the running information from the laser driver, limiting amplifier and CDR. Then report these information to the customer.
